Variables and Patterns 0910

Welcome to the seventh grade math (section 7D, 2009-10) class wiki at the American International School of Dhaka.

Variables and Patterns

Big Idea:Observation and description of changes in the world around us
are the first steps in finding and learning about patterns.

What we KNOW and WANT TO KNOW before we start the unit:
